Surveillance Colonoscopy in Older Adults: The SurvOlderAdults Study

For Aim 1, the investigators will examine colorectal cancer risk among older adults with prior removal of a precancerous polyp (adenoma) vs a prior normal colonoscopy

For Aim 2, the investigators will examine colorectal cancer risk among older adults with prior history of polypectomy, exposed vs unexposed to subsequent surveillance colonoscopy

The investigators will conduct 44 semi-structured one-on-one qualitative interviews with VA patients (older adults) and providers (primary care, GI, geriatrics) to understand perspectives on CRC risk, and potential benefits and harms of surveillance (Aim 3a). The investigators will then convene an expert panel with key stakeholders including Veterans, primary providers, geriatricians, gastroenterologists, VA leaders, and policy makers to present Aim 1, 2, and 3a findings (Aim 3b). The primary outcome will be specific recommendations regarding use of surveillance colonoscopy in older adults, ranked by priority and feasibility, that can guide VA policy around future implementation (or de-implementation) of surveillance among older adults.
